It will be understood that when an element is referred to as being "secured to" or "disposed on" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present.

In addition, it should be noted that the terms of orientation such as left, right, up and down in the embodiments of the present invention are only relative concepts or reference to the normal use state of the product, and should not be considered as limiting. The following describes the implementation of the present invention in detail with reference to specific embodiments.

As shown in the attached figure 1, the utility model relates to a sludge granulator, including feed bin 1, the upper portion of feed bin 1 is provided with opening 2, and opening 2 outwards enlarges, and the mud of being convenient for is poured into. Perforated plate 3 is installed to the bottom of feed bin 1, and evenly arranged has the through-hole 10 that the aperture is the same on perforated plate 3, and perforated plate 3 can be dismantled and change, uses the perforated plate 3 of the through-hole 10 in different apertures to obtain the mud that the particle diameter is different. As shown in fig. 4, the perforated plate 3 has an arc-shaped cross-section, the edge of which is tangential to the side wall of the silo 1. The width of the opening of the silo 1 is larger than the diameter of the cross-section of the perforated plate 3. The pivot 4 is installed along the length direction of feed bin 1 in the top of perforated plate 3, and pivot 4 is located the curved centre of a circle position in perforated plate 3's cross-section, and 4 surface arrangements of pivot have the puddler 5 of the axis direction of perpendicular to pivot 4, and the length of puddler 5 slightly is less than curved radius. When the rotating shaft 4 rotates, the tail end of the stirring rod 5 is stirred at the position close to the arc-shaped perforated plate 3, so that the stirring range is expanded, and the stirring efficiency is higher. If perforated plate 3 is the plane, always there is the mud card in the contained angle department of perforated plate 3 and feed bin 1's lateral wall during the stirring, lead to stirring efficiency to reduce, mud is piled up the normal operating who is unfavorable for the machine for a long time, and the arc is set to perforated plate 3 here, and perforated plate 3's edge is tangent with feed bin 1's lateral wall, makes everywhere can both be contacted by puddler 5, makes the stirring more abundant, and the operation is more smooth and easy.
